Two quick questions. You have probably run these 200 tread wear tires by now. What do you think of them?

Second question, what wheels and wheel width?

Since you are running a square setup, can you rotate front to back, or is wheel offset going to prevent that?

I like the ECF. For HPDE it seems to be one of the best options out there as it lasts a long time. The treadwear is very good, and the reviews seem accurate in that it will heat cycle out well before the treat is gone.

I'm using the Steeda Trident 19x11 +53 square with a 28mm front spacer, so I can rotate front to back. The ECF can also be run backwards when dry from what I've read, although I haven't done it myself. I don't think the Steeda wheels come in a 19x11 with an offset that could be run up front without a spacer. I know Apex wheels, which are popular for track use, have both a 19x11 +52 and +26. With those you could run a square tire setup using +52 in the back and +26 in the front without a spacer, but then you would not be able to rotate front to back.

Steeda Magneride sport progressive lowering springs, adjustable front and rear sway bar, subframe alignment bushings, subframe braces, and camber plates. I have other modifications, but those are the ones pertinent to suspension/chassis.

I am going to be running Continental ExtremeContact Force 295/30/19 square.

Thank you! That is very helpful. I do the same thing when I am setting the front camber where I measure on the ground, then lift and adjust by the desired change. A couple of questions:

1. What are you running for camber and toe in the front?
2. Do you know how much change in toe there is in the rear for a given camber adjustment?

Need a thread update!

There really are not a lot of S650 specific threads on this forum, so, a year later, what did you change and where did you end up on the thread topic of track alignment and camber arms?

Did you try some things that did not work well, or did everything you changed improve your track driving?

So how much rear camber can you get without investing in rear camber arms, just adjusting rear camber using the stock components that Ford installed? I drive an S650 if that is relevant to your answer.

it should be the same as the S550 around -2.0 degrees honestly don't think you need much more. The reason people upgrade to Camber Arms is because of the rubber bushings in the OEM ones and ease of adjustment.

I am just sharing this here because a forum member at mustang7G.com posted an image to show how to adjust rear camber, and I thought maybe others here might want to see it.

It is post # 6.

One bolt through a slot. Loosen it two turns to push or pull the upper portion of the wheel and tire in or out, then tighten the bolt. The visual representation makes it worth the click.

This is the setup sheet for a Dark Horse R and the minimal You should start for a real track car though -3.5 camber upfront is exessive you can get away with -3.2 or so.

Front -3.5 and rear only -1.75

(1) The rear camber kind of surprised me.

(2) I wonder if these settings changed when they changed to stickier tires on 18" wheels?
